Decomposed Granite – Gray is a popular material because it creates a firmer surface than most gravel, but still allows water to permeate through.  These crushed stones are irregular-shaped with jagged edges ranging from dust to 3/8” in size, which allows for easier compaction. Our Decomposed Granite – Gray works great in pathways, residential driveways, filler between patio stone, dog runs, bike trails, and garden trails. This crushed granite has varying colors of grays to black with a slight shimmer.    Approximate coverage of 110 sf/ton.
